Gneiss is a metamorphic rock. It is formed form another metamorphic rock called schist (sh-ist). Schist is formed form fine grained sedimentary rock (often shale). While gneiss is formed by great pressure from moving plates of the earth's crust.

How does gneiss differ from the rock it was formed?

They are both metamorphic rocks. One difference is the rocks they are formed from. Gneiss is formed from Feldspar and Quartz. Gneiss can also contain muscovite, biotite and hornblende. Quartzite is formed from sandstone. Also Gneiss is more intensely foliated than Quartzite. This can be seen in the bands formed in Gneiss, while quartzite has no bands. Pure quartzite is white, while Gneiss is grey or pink, with dark streaks.
